Abstract:
Bananas (Musa spp.), including dessert and cooking types, are giant
perennial monocotyledonous herbs of the order Zingiberales, a
sister group to the well-studied Poales, which include cereals.
Bananas are vital for food security in many tropical and subtropical
countries and the most popular fruit in industrialized countries1.
The Musa domestication process started some 7,000 years ago in
Southeast Asia. It involved hybridizations between diverse species
and subspecies, fostered by human migrations2, and selection of
diploid and triploid seedless, parthenocarpic hybrids thereafter
widely dispersed by vegetative propagation. Half of the current
production relies on somaclones derived from a single triploid
genotype (Cavendish)1. Pests and diseases have gradually become
adapted, representing an imminent danger for global banana production3,4.
Here we describe the draft sequence of the 523-megabase
genome of aMusa acuminata doubled-haploid genotype, providing
a crucial stepping-stone for genetic improvement of banana. We
detected three rounds of whole-genome duplications in the Musa
lineage, independently of those previously described in the Poales
lineage and the one we detected in the Arecales lineage. This first
monocotyledon high-continuity whole-genome sequence reported
outside Poales represents an essential bridge for comparative
genome analysis in plants. As such, it clarifies commelinidmonocotyledon
phylogenetic relationships, reveals Poaceaespecific
features and has led to the discovery of conserved noncoding
sequences predating monocotyledon–eudicotyledon
divergence.
